The final novel in Terry Brooks' thrilling trilogy about the voyage of the airship "Jarl of Shannara" reveals to the reader an amazing world of adventure, wonder and danger. Not many of those who went in search of ancient magic aboard the Jarl of Shannara survived the battle with Anthrax, a feral computer, the last guardian of the knowledge of a lost civilization. The druid nicknamed the Wanderer was able to destroy Anthrax at the cost of his own life, and the surviving members of his expedition are now scattered across a foreign, unfamiliar and dangerous land. Finding each other and the way home is not easy - they are pursued by the powerful and cruel sorcerer Morgavr, eager to master the magic of the Old World and take revenge on his rebellious student - the witch Ilsa.
